Description

HB620 Cut-Off Red Optical Glass Filter

The HB620 Cut-Off Red Optical Glass Filter is a type of optical filter that is designed to block or significantly attenuate light with wavelengths shorter than a specific cut-off point in the red spectrum. This filter is commonly used in applications where precise control over the transmission of red light is required, such as in scientific experiments, industrial processes, or photography.

The HB620 filter is made from red optical glass that is engineered to absorb or block light below a certain wavelength threshold, typically around 620 nanometers (nm). This means that it allows red light with longer wavelengths to pass through while effectively filtering out shorter wavelength colors, such as orange, yellow, green, and blue.

The cut-off characteristic of the HB620 filter enables it to selectively transmit light in the red spectrum while blocking unwanted shorter wavelength light. This can be particularly useful in applications where specific colors need to be isolated, light pollution needs to be reduced, or contrast enhancement is desired.

When using the HB620 Cut-Off Red Optical Glass Filter, it is important to consider the filter’s transmission curve, the exact cut-off wavelength, and any potential spectral leakage or transmission beyond the cut-off point.
